Expand description

Round the lower double-precision (64-bit) floating-point element in b using the ROUNDING parameter, store the result as a double-precision floating-point element in the lower element of the intrinsic result, and copies the upper element from a to the upper element of the intrinsic result. Rounding is done according to the rounding parameter, which can be one of:

#[cfg(target_arch = "x86")]
use std::arch::x86::*;
#[cfg(target_arch = "x86_64")]
use std::arch::x86_64::*;
